Abstract:
An electronic timepiece has; an annular antenna; and a time display unit. The antenna includes an annular dielectric; a conductive driven element that is disposed on the dielectric, is ring-shaped with a notch therein (C-shaped), and is fed with a specific potential; and a conductive parasitic element that is disposed on the dielectric with a gap to the driven element, and is an endless ring or a ring with a notch therein (C-shaped). A feed position to which a specific potential is fed is disposed to the driven element at one place. When the electronic timepiece is seen in plan view, the feed position is disposed in a range from approximately 8:00 to approximately 10:00 relative to the center (center pivot) of the electronic timepiece.
